  1. 11. Progressive landslides in long natural slopes : Formation, potential extension and configuration of finished slides in strain-softening soils

    Författare :Stig Bernander; Steinar Nordal; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik; Soil Mechanics; Geoteknik;

    Sammanfattning : After the large landslide in Tuve (Gothenburg, 1977), the author began developing a finite difference model for slope stability analysis taking the deformation-softening of soft sensitive clays into consideration. In the model, the mean down-slope deformation in each element caused by normal forces is maintained compatible with the deformation generated by shear stresses. LÄS MER

  3. 12. Progressive landslides in long natural slopes : potential extension and configuration of finished slides in strain-softening soils

  5. 14. Strengthening of concrete structures by the use of mineral based composites

    Författare :Thomas Blanksvärd; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Strengthening of concrete structures with epoxy bonded carbon fiber reinforced polymers (CFRP) has been proved to be an excellent strengthening technique. However, using epoxy adhesives for bonding do contain some disadvantages such as diffusion closeness, thermal incompatibility to the base concrete, regulations regarding the working environment and minimum application temperature.

    Sammanfattning : A great number of society's resources are invested in existing concrete structures, such as bridges, tunnels, different kind of buildings etc. All of these structures have both an expected function and an expected life span. However, both the function and the life span can be influenced by external factors, e.g. LÄS MER
